Sherlock Sam and the Alien Encounter on Pulau Ubin (Book 4)

“The humour and camaraderie of the children, the robots and the lovable parents are reassuring, and makes you wish you could be part of the group in their next adventure.”
— Naomi Kojima, Japanese author and illustrator of The Alphabet Picture Book and Singing Shijimi Clams

“What’s not to love about a savvy kid with pluck, prepared to step outside humdrum routines to solve mysteries? Young readers everywhere dream of pushing limits in pursuit of adventure, and Sam is all the more appealing for his habit of running rings around grown-up buffoons. In Sherlock Sam, A.J. Low has conceived a series sure to have long-term appeal.”
— Ken Spillman, author of the Jake series

“From the first missing heirloom in Katong to this current cloaked classmate in MacRitchie, Sherlock Sam continues to captivate its readers. Definitely a middle-grade series that I would unreservedly recommend to teachers, parents, and fellow bibliogeeks. Science!”
— Myra Garces-Bacsal, PhD, National Institute of Education, Singapore
